I did not use it first @exchmist referred to it, and I simply quoted it to refute his contentions. The reference affirmed that science gives an objective understanding of consciousness. There are still unknowns, but science works.
Read it carefully . . .
"Consciousness as we have been discussing it is a biological process, explained by neurobiological and other cognitive mechanisms, and whose raison d’etre can in principle be accounted for on evolutionary grounds. To be sure, it is still largely mysterious, but (contra Dennett and Churchland) it is no mere illusion (it’s too metabolically expensive, and it clearly does a lot of important cognitive work), and (contra Chalmers, Nagel, etc.) it does not represent a problem of principle for scientific naturalism."
